Why Choose the nVent HOFFMAN A3003YZHM Large-Volume System?
The nVent HOFFMAN A3003YZHM Large-Volume System is a professional horizontal-mount Type Y and Type Z purging and pressurisation system designed to provide protective gas supply and pressure control for large electrical enclosures installed in hazardous industrial environments. It enables suitable general-purpose enclosures to be used in certain classified hazardous locations by maintaining a protective internal atmosphere.
The A3003YZHM supplies one or more protected enclosures with compressed instrument air or inert gas, helping remove and prevent the accumulation of flammable vapours inside the enclosure. The system is designed for enclosure volumes up to 90 ft³ (2.55 m³) and supports NEC Type Y and Type Z applications where approved installation requirements are met.
Featuring a horizontal mounting configuration, the A3003YZHM includes a Type 316L stainless steel face plate and mounting plate, together with integrated regulation, monitoring and connection components for reliable enclosure pressurisation control.
